Here are some peripheral points of support.<br>
<br>
Last weekend i updated and deployed the x3d.py package (sometimes called X3DPSAIL) at<br>
<br>
[1] Python Package Index (PyPi) x3d 0.0.25<br>
Package support for Extensible 3D (X3D) Graphics International Standard (IS)<br>
<a href="https://pypi.org/project/x3d/" rel="noreferrer" target="_blank">https://pypi.org/project/x3d/</a><br>
<br>
[2] Python X3D Package x3d.py,X3D Python Scene Access Interface Library (X3DPSAIL)<br>
<a href="https://www.web3d.org/x3d/stylesheets/python/python.html" rel="noreferrer" target="_blank">https://www.web3d.org/x3d/stylesheets/python/python.html</a><br>
<br>
"The x3d.py Python X3D Package supports programmers with Python interfaces and objects for standards-based X3D programming, all as open source.<br>
The presentation *Python X3D Package Implementation* provides an overview and shows examples."<br>
<br>
[2.1] Python X3D Package Implementation<br>
<a href="https://www.web3d.org/x3d/stylesheets/python/documents/PythonX3dPackageImplementation.pdf" rel="noreferrer" target="_blank">https://www.web3d.org/x3d/stylesheets/python/documents/PythonX3dPackageImplementation.pdf</a><br>
<br>
So you would use this library for model creation and data-driven improvement, no need to reinvent X3D data structures or methods.<br>
<br>
This is autogenerated from X3DUOM so it will always stay in sync with latest/greatest X3D4.<br>
<br>
We've done some preliminary work with Jupyter notebook, listed there. Lots of potential projects in TODO section.<br>
<br>
[2.2] X3DPSAIL: Jupyter notebook, TODO<br>

<br>
For pythonocc conversion efforts, will be happy to ensure that<br>
a. all improvements to API are applied,<br>
b. ensure that validation of all scene-graph inputs remains rigorous,<br>
b. utility methods are added for easy use together,<br>
d. examplar conversion models are properly saved in X3D Examples Archive,<br>
e. Whatever else!<br>
<br>
Looks like there is vast potential here. Hoping folks start picking it up and applying capabilities.<br>
<br>
Have fun with X3D Python! 8)<br>
